The reference · every weight with its document
A cup of flour is 120 grams. Or 125, or 142, or 161, depending on whose chart you read and how they filled the cup. Name an ingredient and an amount and this shows you every published figure for it, in the source's own words, with what each one did and did not say about its cup and its hand. Where they agree you get a number. Where they do not, you get the range, and the reasons.
A named ingredient from the curated table, or any food in USDA's own list.
Fractions are fine: 1½, 3/4, 2 1/3.
Grams runs the other way: how many cups is that?
A recipe was tested with one of these in its author's hand. Pick that one and you get its number, as it prints it. We will not pick for you.

Three things move a cup weight, and most charts state at most one of them. The product: two mills' all-purpose flour, spooned the same way, weigh differently. The cup: a metric cup holds more than a US customary cup; the Western sources here state cups of 236, 237, 240 or 250 mL, and the four Japanese sources state a 200 mL cup, a fifth smaller than the metric one. No figure is rescaled from any of them to any other. The hand: the same cup, filled by dipping it into the bag or by spooning flour into it, comes out heavier or lighter by more than the cups differ. The sources that measured this themselves:

Paste the ingredient lines. Each line with an amount and a cup, tablespoon or teaspoon gets its range; a line without one is left alone and says so.
The word means three different volumes in ordinary kitchens across four systems (Australia's cup is the metric 250 mL with a bigger spoon), and a fourth on a US nutrition label. Each definition below is quoted from the document that sets it. None of them is applied to a source's figure: a number stays in the cup its source used. Choose yours above and the table says which sources state that cup, and can narrow to them; it will not rescale the rest.
The Japanese sources here agree with one another to the gram on every row they share but one (ketchup: 230 g a cup at the ministry and at Ajinomoto, 240 at DELISH KITCHEN), and one of them says where its figures come from: the agriculture ministry’s table credits 参考：女子栄養大学出版部 調理のためのベーシックデータ第4版
, Kagawa Nutrition University Press’s Basic Data for Cooking, 4th edition. The recipe sites print the same figures and name no source. The page counts the reprints it kept as the sources that printed them, and leaves six municipal and one prefectural sheets, which print the same figures for nearly every row they share with the ministry’s, in the harvest uncounted.

A state this grammar cannot carry clears the query rather than leaving a stale one, so a link you copy always points at the answer you were shown. cups.artwaste.land serves this same page and the same grammar, and is the shorter thing to hand somebody.
